If you're busting out some long rides on your road bike, you need a set of tires that won't bail on you halfway through your workout. These tires roll fast and protect your tubes from punctures, making them great for training and endurance riding.

I enjoy long distance riding, but live in a climate with a short road cycling season. Bought these on a whim before the season started last year because price was so good versus the name tires I usually bought. I have over 3,500 miles on them and they are still going! I just bought another set to have as abackup. They are going to wear out, eventually!

I use these tires on my carbon road bike with Oval Wheel set. At 195 lbs. I can be tough on tires. I pump these tires up to 125 lbs. and they don't complain. No more problems with pinch flats like on my lower pressure tires. With over 1500 miles on these I've had zero problems. No flats! Yes I have ridden over glass, hit pot holes and they survived unscathed. I'm surprised at how much they smooth the road out at 125PSI. I have lost a little rubber due to road gravel taking tiny chunks out near the side of the tread. But I'm very pleased with their performance. I'm pleased with my purchase.

for tires. These are just as rubbery, round, and black as the high priced tread. They perform and wear just as well. I've purchased tires that were supposed to get 6,000 miles that were done with me at around 2,000 of a 3,700 mile trans-continental trip, and that's what I expect from these but at well below half the price. I'm tired of paying too much for tires, so I buy these four at a time without breaking the bank.

I decided to try some new tires and picked these out - my mistake. I've now had 4 punctures in only 500 miles of riding. Last night I decided to ride them one last time before swapping them out for something else and FLATTED AGAIN due to a puncture, it's especially weird that it's the front almost every time. I'm riding the same roads (urban with glass, stones, chip/seal, etc.) I've ridden for 10 years and have NEVER had so many flats, I've gone whole seasons without flatting. I've noticed that for some reason these tires are a magnet for debris. It's almost like the rubber holds onto the debris until the rotation of the tire forces it through the rubber and the tube. I've inspected the tire a few times before riding and noticed 10 or more cuts/debris stuck in the tire that I've picked out before riding so they don't work through and cause a puncture. I've never had that problems with other brands - have used Maxxis, Panaracer, Vittoria and others in the past with better luck. Good thing I bring spare tube/pump/tire levers on every ride because I needed them often with these!

The quality is very good for the price. Good traction when cornering. Can't speak about durability yet since they're new for me. Not as supple as some other 120 tpi tires I've tried, but not bad.

I didn't buy the 700x23 size, but be aware that the 700x25 size runs small. Some manufacturers have been known to make tires slightly smaller than spec, in order to weigh in at a lighter weight for a claimed size of width. For example, when spread flat on a table, these tires measure 63mm in width. I have a set of Michelin Lithion 2 tires, also 700x25, that measure 73mm in width when spread flat, a full centimeter wider! Thus, when inflated to the same pressure, the larger volume of air in the Michelins compared to these Nashbars would provide more of the benefits of using a wider tire (reduced rolling resistance, reduced risk of pinch flats, more comfortable ride over bumps, better grip and handling).

When mounted on a rim with 19mm external width, the Nashbar Duro Pro runs slightly narrow. I have digital calipers that measure to the hundredth of a millimeter, and found that when the Nashbars were inflated to the max recommended PSI (130 PSI, which I would never actually ride at), the width was 24mm. At 120 PSI (the max I would personally prefer to ride for comfort reasons) the width dropped to a little over 22mm. Thus the benefit of wider tires having less rolling resistance than traditional 23mm tires (due to a shorter but wider contact patch) is negated, since the tires are actually quite narrow unless pumped to 130 PSI (which would then result in a harsher, bumpier ride). The Michelins, when mounted on the same rim and inflated to the max recommended PSI (105 PSI, much more comfortable), had a width of 25mm, as claimed. But the height of the tire was about 2mm or so higher than the Nashbar, due to the overall greater width of 10mm when spread flat compared to the Nashbar.

Incidentally, as a point of interest, having a smaller circumference tire creates the effect of riding in a slightly smaller gear, since it takes less work to turn the wheel with each revolution. But the effect is pretty small and not really noticeable.

The main point to note is that these Nashbar tires have a significantly smaller total air volume than some other 25c tires, even though the width is only slightly narrower than 25mm on a 19mm rim.

I also mounted both sets of tires on another set of wheels, Shimano rims that were 20.8 mm in external rim width. In that case, at the recommended max pressures, the Michelins measured at 27mm width at 105 PSI, and the Nashbars measured at 26mm width at 130 PSI. So the width and sidewall height will vary and width could be more or less than 25mm depending on the rim you're using. But on any rim, the overall reduced volume of the Nashbar compared to some other tires makes them ride more like 23s than 25s, which could be good or bad, depending on your needs.

I'd recommend these tires if you don't mind tires that run a little small. For me, I won't be buying these again because I want 25c tires that are larger than these. The heavier weight of wider tires is a drawback on super hilly rides, but since I'm not a racer, I don't care a lot about that. But it's still a consideration, and for the same weight of 250 grams, and for about the same price (eg-Michelin Lithion 2 is selling for $18 right now at a couple places online) you could get 700x25 tires that are larger, more supple, and more grippy (although maybe not as durable).

But overall the quality seems good, and for the price they're a good value.

These do not ride like 120 TPI tires, not even close. They are rocks. I have heard where certain manufacturers place two 60 TPI layers in the tire and call it 120 TPI. The result is a tough but hard tire, which is what I suspect these are. I know 120 TPI and better tires, and these are not 120 TPI.

So I wanted to do a review as I have been using these tires for 8 months now. I have seen a few bad reviews about how heavy they are or they don't ride like a 120TPI tire. I have to say they have exceeded my expectations. I have been running them at 95-100 PSI and they handle great! They are not harsh on the roads and NJ has some badly chewed up ones at them moment. They have great cornering abilities and grip is fantastic. The rolling resistance its ok, the more I ride them I find that my Gators did have a faster rolling rate but its not something Id say would steer me away from them. I have hit a few nasty things that I thought was going to leave me patching a tube or booting the tire, I am careful while riding but hey things happen and some times you don't catch everything on the road. I even had a sharp rock dig its self into the center and make a few rotations around before I was able to stop and pluck it out. No bulge and no flat! I have gotten ONE flat since I started using them. It was the 1st or 2nd ride and I nailed something that honestly would have taken out the thickest tire no matter what. I booted it and have put a ton of miles on it since with no problems. Also in the wet conditions I have never felt more confident, no slipping and even at high speeds they are holding the road. I Have had some tires that felt like you are on ice in the wet, while these just keep planted!

One thing I can say is a down side to these tires is off the bat they are hard to mount by just hands on some rims. I recently had mounted two sets on some carbon clinchers and one of the sets was almost nearly impossible. I had the nastiest blisters on my thumbs and soft tissue damage. With a set of leavers they are cake and mount up quickly. I will say once they are inflated and used they are easy to dismount and remount by hand. Its just the 1st time around on some rims.

If you can get these on sale snag them. I have them on all my road bikes and its my go to tire. I was sick of paying top dollar for similar tires and having side wall failures or paying twice as much for one when I can get a pair and they last just as long if not longer. I have used these on the trainer a (few times but I tend to use rollers if I do indoor riding), a bunch of times on the rollers and a TON of the road. You can use them for training or if you wanted to even racing. I know I will be this year! Sure it doesn't have the big name logo on it but from what I have seen and heard they might just be a Maxxis Detonator so keep that in mind. Look up the reviews of them and if they seem to fancy you then spend half the price and get the House Brand!

I was expecting more out of these tires. They weighed 30 grams more than advertised on my scale and sure don't ride like a 120 tpi tire. I gave 3 stars as I have 2000 miles on them and they show little wear. I have the Prima 2 tires on my beater bike and they ride just as nice as these and are just as fast. Save your money and go with the Prima 2 if you are looking for a cheap durable tire.

Never been disappointed by a Nashbar product before, but this tire was an exception. I found it heavy and unresponsive. They weren't particularly comfortable either. Previous tire Michelin Krylion Carbon (nice) replacement tire Continental Grand Prix (sweet). For less than $40, per tire on an alternate site I am back in business. I figure I'm saving about 50gm per wheel too. 100 gms equals a quarter pound. The tires are mounted on relatively inexpensive Mavic Ksyrium Equipes. The handling, acceleration and comfort improvement was immediately apparent. Not worth the savings
